Abstract

A novel and sensitive magnetic ionic liquidbased upanddownshakerassisted dispersive liquidliquid microextraction MILUDSADLLME was developed for the graphite furnace atomic absorption spectrometric measurement of inorganic selenium speciation from various rice matrixes In the first microextraction step the magnetic ionic liquid 1butyl3methylimidazolium tetrachloroferrate C4mimFeCl4 was selected to extract the complex of SeIV and 23diaminonaphthalene from aqueous solution by the assistance of upanddownshaker vortex agitator After the microextraction step the magnetic ionic liquid containing target analytes was collected at the bottom of the tube by applying an external magnetic field around the test tube Under the optimized conditions the method present has low detection limit 0018 μg L−1 wide linear dynamic range 003–10 μg L−1 and good repeatability 30 n = 10 for SeIV The proposed methodology was applied for separation and preconcentration of inorganic selenium in standard reference materials including GBW10010 rice GBW10043 Liaoning rice and GBW10045 Hunan rice with satisfactory results The developed methodology was also successfully used for the speciation of SeIV and SeVI in different rice samples with the relative recoveries within the acceptable range of 949–1048 for the addition recovery testsThis work was supported by the Key Project of Research and Development Program of Zhejiang Province under grant number 2015C03G2610002 and the National University Students’ Innovation and Entrepreneurship Training Program under grant number 201511481009Xiaojun Wang declares that he has no conflict of interest Peng Chen declares that she has no conflict of interest Liang Cao declares that he has no conflict of interest Guoliang Xu declares that he has no conflict of interest Siyu Yang declares that she has no conflict of interest Ye Fang declares that she has no conflict of interest Guozhen Wang declares that she has no conflict of interest Xincheng Hong declares that he has no conflict of interest
